Application filed September 3, 1927. Serial No. 217,345.

slidably mounted on the swing-member and spring-actuated downwardly inthe direction of the base-bracket, and means by which the pull-memberimparts to the flap-bracket a constant pressure in slantwise direction,downwardly and inclined inwardly in respect to the hood; v

In the attached drawing; Y

Fig. 1 is an elevation of the hood fastener when in fastened position.Fig. 2 is a side elevation ofthe same.

Fig. 3 is a sectional side elevation showing the hood fastener inunfastened position.v

Fig. 4 is a sectional plan through 4-4 of Fig. 2.' v l Fig. 5 is asectional plan through 55 of Fig. 2.

Referring to the drawing, 1 is a portion of the flap of the hood. 2 is aportion of the base extension of the hood. 3 is the flap-bracket. 4 isthe base-bracket. 5 is the swing-member pivoted on the pin 6, betweenthe two washers 7, to the base-bracket. 8 is a collar secured to theswing-member. 9 is a member slidably mounted on the swing-member. 10 isthe pull-member and is slidable on the collar 8. 11 is a member securedto the upper end of the pull-member. The member 9 is secured to thelower end of the pull-member and as the members 9 and 11 are eachsecured to the pullmember and thus partake of its movements, they mayberegarded as portions of the pullmember, as likewise the collar 8 aportion of the swing-member, and thus the pull-member is slidablymounted on the swing-member. 12 is a helical spring which cooperateswith the swing-member 5 by means of itscollar 8 to press the pull-memberdownwardly 'towards the base-bracket. The portion 11 of the pull-memberis provided with prongs 13 by which the operator manipulates the pullmember to fasten and unfasten the hood. The portion'll ofthe pull memberis provided with arms 14 with which the pull member cooperates with theflap-bracket to fasten the hood. The flap-bracket is provided with apair of arms which extend embracingly, when the fastener' is-in fastenedposition, one on each side of the pullmember, and terminate in portions15 to which the arms 14 of the spring actuated pull-,member imparts apressure in slant-wise direction, downwardly and inclined inwardly inrespect tothe hood. 16is .an extension of the base-bracket which servesras a support to hold the pull-member when unfastened to theflap-bracketin the most conve-nient position for manipulating.

It should be noted (see Fig; 2) that the line of pressure, indicated bythe arrow and numeral'17v, imparted by the spring by means of thepullmember to the flap-bracket, or, which is the same thing, the lineoftension from the Contact of the pull member with tlieilapbracket tothe base-bracket, leans farther away from the flap lof the hood,.thandoes the line-of pressure, indicated by the arrow and numeral 18, of thespring pressing the pullmember towards the base-bracket.

It should be understood that in order to eiciently fasten the flap ofthefhood of an automobile, the direction of the pressure applied to theflap should be inwards as well v as downwards; otherwise a disagreeablerattling noise will occur whenthe automobile is in rapid motion. Theproportion of the yinward to the downward pressure required va# ries inaccordanceto theshape of the` hood but is constant for that particularform of hood. A yielding pressure applied in the correct slantwisedirection will give the required proportionate inward and downwardpressures. Hitherto, in most instances, this yielding pressure could notbe applied in the correct slantwise direction with a fastener consistingmerely of a flap-bracket, a basebracket, a swing-member pivoted to thehasebracket and a spring-actuated pull-member carried on theswing-member; and to remedy this, in many hood fasteners, added partssuch as cams and links co-operate with the pull-member. But the fastenerhere illustrated and described, applies the pressure in the correctslantwise direction and also does not require the added partsl in orderto be generally applicable.

' What I claimis:

` 1. In a hood fastener of the type which fastens the flapv by impartingpressure on it in slantwise direction both downwards and inwards inrespect to the hood, a flap-bracket securedto the flap, a base-bracketsecured to the base extension of the hood, a swing member pivoted on apivot in the base bracket in the pull-member downwardly in the line'oi3direction towards the pivot of the basebracket, and means by which theline ot' direction of the pressure exerted by the pull-member on theilapbracket towards the said pivot leans outwardly in respect to v theiiap of theI line of direction of `the pressure exerted by the springont-he pull-meniber towards the said pivot.

2. n a hood fastener of the type which fastens the flap by impartingpressure on it in a slanting direction both downwards and inwards inrespect to the hood, a flap bracket secured to the flap, a base-bracketsecured to the base extension of the hood, a swing' member pivoted on apivot inthe base-bracket in a manner permitting a swing-like movement toand from t-he flap, a pull-member slidably mounted on the swing-member,a spring` carried by the swing-member and pressing the swing-memberdownwardly in the line of directionV towards the pivot ot' thebracebracket, the said flap-bracket having,` a pair of arms extending`one on each side oi' the pull-member, the said pull-member having a pairof arms extending crosswise and adapted to fasten the flap vbyexerting;r pressure on the ends of thearms of the iiap bracket in theline et' direction towards the pivot oi the base bracket, and meansv bywhich the line of directionv of the pressure exerted by the arms ot''the pullv member on the arms of the flapbraoket towards the said pivot,leans outwardly in respect tothe flap of the line of direct-ion ot thepressure exerted by the spring onthe pull-member towards the said pivot.

3. In a hood fastener of the type which fastens the flap by imparting;lpressure on it in slantwise direction both downwards and inwards inrespect to the hood, a flap-bracket arms of the a )-bi'acket to i'astcnthe flap,

the said arms oi: the pull-member located on the side of the pull-memberwhich is farthest from the i'lap.
